Does Anti-VEGF Injections Increase the likelihood of Tractional Retinal Detachment in Proliferative Diabetic Retinopatht?

Is there an increased risk for tractional retinal detachment (TRD) in proliferative diabetic retinopathy (PDR) associated with intravitreal injections alone compared with other treatment regimens? That's the question that researchers at Perelman School of Medicine at the University of Pennsylvania sought an answer for. 

Embryonic stem cells for treating blindness

Researchers at Karolinska Institutet and St Erik Eye Hospital in Sweden have discovered a way to refine the production of retinal cells from embryonic stem cells for treating blindness in the elderly.

Using CRISPR/Cas9 gene editing, they also modified the cells so that they can hide from the immune system to prevent rejection.

Immune system may slow degenerative eye disease

A new study shows that the complement system, part of the innate immune system, plays a protective role to slow retinal degeneration in a mouse model of retinitis pigmentosa, an inherited eye disease. This surprising discovery contradicts previous studies of other eye diseases suggesting that the complement system worsens retinal degeneration. 

The research was performed by scientists at the National Eye Institute (NEI), part of the National Institutes of Health, and appears in the Journal of Experimental Medicine.
